WILLIAM S. NEEL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO FRANCIS YV. MURPHY, OF SAME PLACE.

BOOK-SEWING SLIP.

SPECIFICATION forming part of Letters Patent No. 257,140, dated April 25, 1882,

Application filed December 22, 1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. NEEL, a citizen of the United States, residing in the city and county ot'Philadelphia, State ofPennsylvauia, have invented a new and useful Improvement in Book-Sewing Slips, which im provement is fully set forth in the following specification and accompanying drawings, in which-- Figure l is a view of the back of the body ofa book having my invention applied to it. Figs. 2 and 3 are views of the slips embodying my invention. Fig. 4 is a section in line a: 0:, Fig. 2. Fig. 5 is a section in line 3 y, Fig. 3.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a slip for sewing sheets, sections, or signatures of books, formed of a strip of parchment or other integuincnt or material of a tough and strong nature, and a textile guard therefor, whereby the signatures are connected in a durable and reliable manner and the threads are prevented from being worn or cut by the edges of the pazchment strip.

Referring to the drawings, A represents the body of a book, and B the threads employed for sewing together-the sheets, sections, or signatures thereof.

0 represents slips, which are placed against the back of the body, and the threads 13 are passed around slips, as shown in Fig. 1, each slip being formed of two parts, a b, set face to face, the inner strip, a, being parchment or other suitable integument and the outer piece, b, being tape or other textile material. The piece I) is somewhat wider than the strip a, so that its edges extend beyond those ofthe strip, and the piece and strip maybe connected by pasting, gumming, &c; butthe piece I) may be suificiently wide so as to be turned over and overlap the edges of the strip a; or the piece I) may be woven or otherwise constructed of tubular form, as in Figs. 3 and 5, and thusinclose the strip.

It will be seen that as the strips (0 are of great toughness and strength, and they are combined with the pieces I), the book is sewed in a strong and durable manner. Furthermore, the textile pieces I) act as guards for preventing contactof the threads B with the edges of the strips a, which edges, being somewhat sharp, would, if exposed, wear and cut the threads, and thus the reliability of the sewing of the book is increased.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Book-sewing slips formed of strips of integument, and guard-pieces of textile material, substantially as and for the purpose set forth.
